+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+ComfyUI-KikoTools is a planned modular collection of custom ComfyUI nodes that will provide essential tools missing from the standard ComfyUI release. All nodes will be grouped under "ComfyAssets" in the ComfyUI interface. The project is designed for extensibility, allowing new tools to be added easily while maintaining clean separation of concerns.
+
+**Current Status**: Project is in initial planning phase. Only documentation and licensing files exist.
+
+## Architecture
+
+### Design Principles
+- **Modular Design**: Each tool is a separate, self-contained module
+- **ComfyAssets Grouping**: All nodes appear under the "ComfyAssets" category
+- **Test-Driven Development**: Every tool includes comprehensive tests
+- **Clean Interfaces**: Standardized input/output patterns across tools
+
+### Core Components
+- **Tool Registry**: Central registration system for all KikoTools nodes
+- **Base Classes**: Shared functionality for consistent tool behavior
+- **Individual Tools**: Self-contained modules for specific functionality
+
+### Current Tools
+
+#### 1. Resolution Calculator (First Tool)
+- **Purpose**: Calculate upscale resolution from image or latent inputs
+- **Inputs**: 
+  - Image or Latent tensor
+  - Scale factor (1, 2, 3, 1.2, 1.5, 2.0)
+- **Outputs**: 
+  - Width (INT)
+  - Height (INT)
+- **Target Models**: Flux and SDXL optimized
+- **Use Case**: Connect calculated dimensions to upscaler nodes
+
+## Technology Stack
+
+- **Backend**: Python with ComfyUI node patterns
+- **Node Framework**: ComfyUI INPUT_TYPES, RETURN_TYPES, execute() patterns
+- **Testing**: pytest with ComfyUI test fixtures
+- **Code Quality**: black, flake8, mypy
+- **Integration**: ComfyUI execution queue and tensor systems
+
+## Development Commands
+
+**Note**: These commands are planned for when the project structure is implemented.
+
+### Initial Setup
+```bash
+# Create basic project structure
+mkdir -p kikotools/{base,tools} tests/{unit,integration,fixtures} scripts examples
+
+# Create entry point files
+touch __init__.py kikotools/__init__.py
+```
+
+### Code Quality (Future)
+```bash
+# Format Python code
+black .
+
+# Python linting
+flake8 .
+
+# Type checking
+mypy .
+```
+
+### Testing (Future TDD Workflow)
+```bash
+# Run all tests
+pytest tests/
+
+# Run tests for specific tool
+pytest tests/unit/tools/test_{tool_name}.py
+
+# Test coverage
+pytest --cov=kikotools tests/
+```
+
+## Project Structure (Planned)

+
+## Key ComfyUI Integration Points
+
+### Node Registration Pattern
+```python
+# Each tool follows this pattern in kikotools/tools/{tool_name}/node.py
+class ResolutionCalculatorNode:
+    @classmethod
+    def INPUT_TYPES(cls):
+        return {
+            "required": {
+                "scale_factor": ("FLOAT", {"default": 2.0, "min": 1.0, "max": 8.0, "step": 0.1}),
+            },
+            "optional": {
+                "image": ("IMAGE",),
+                "latent": ("LATENT",),
+            }
+        }
+    
+    RETURN_TYPES = ("INT", "INT")
+    RETURN_NAMES = ("width", "height")
+    FUNCTION = "calculate_resolution"
+    CATEGORY = "ComfyAssets"  # All tools use this category
+    
+    def calculate_resolution(self, scale_factor, image=None, latent=None):
+        # Implementation here
+        pass
+```
+
+### Base Node Class
+- Provides consistent "ComfyAssets" categorization
+- Standardizes error handling and logging
+- Implements common validation patterns
+- Ensures consistent return type handling
+
+### Tool Registry System
+- Automatic discovery of tools in `kikotools/tools/`
+- Dynamic node registration during ComfyUI startup
+- Version compatibility checking
+- Dependency validation
+
+## Test-Driven Development (TDD) Workflow
+
+### 1. Write Tests First
+```python
+# tests/unit/tools/test_resolution_calculator.py
+def test_resolution_calculator_with_image():
+    """Test resolution calculation with image input."""
+    # Arrange
+    node = ResolutionCalculatorNode()
+    test_image = create_test_image(512, 512)  # fixture
+    scale_factor = 2.0
+    
+    # Act
+    width, height = node.calculate_resolution(scale_factor, image=test_image)
+    
+    # Assert
+    assert width == 1024
+    assert height == 1024
+
+def test_resolution_calculator_with_latent():
+    """Test resolution calculation with latent input."""
+    # Similar pattern for latent inputs
+    pass
+```
+
+### 2. Run Tests (Should Fail)
+```bash
+pytest tests/unit/tools/test_resolution_calculator.py -v
+```
+
+### 3. Implement Minimal Code
+```python
+# kikotools/tools/resolution_calculator/logic.py
+def calculate_upscale_resolution(input_tensor, scale_factor):
+    """Calculate new resolution based on input and scale factor."""
+    # Minimal implementation to pass tests
+    pass
+```
+
+### 4. Refactor and Expand
+- Add error handling
+- Optimize for Flux/SDXL specific requirements
+- Add comprehensive validation
+- Implement edge case handling
+
+### 5. Integration Testing
+```python
+# tests/integration/test_workflow_execution.py
+def test_resolution_calculator_in_workflow():
+    """Test resolution calculator in full ComfyUI workflow."""
+    workflow = load_test_workflow("resolution_calculator_example.json")
+    result = execute_comfyui_workflow(workflow)
+    assert result.success
+```
+
+## Tool-Specific Implementation Notes
+
+### Resolution Calculator
+- **Input Validation**: Handle both image and latent tensors
+- **Scale Factors**: Support integer (1, 2, 3) and float (1.2, 1.5, 2.0) multipliers
+- **Model Optimization**: Consider Flux and SDXL specific resolution requirements
+- **Output Format**: Integer width/height suitable for upscaler node connections
+- **Error Handling**: Graceful handling of invalid inputs or edge cases
+
+### Future Tools (Planned)
+- Batch Image Processor
+- Advanced Prompt Utilities
+- Model Management Tools
+- Custom Sampling Methods
+
+## Development Workflow
+
+### Adding a New Tool
+1. **Plan**: Define tool purpose, inputs, outputs, and test cases
+2. **Generate**: Use `python scripts/create_tool.py --name "NewTool"`
+3. **Test**: Write comprehensive tests following TDD principles
+4. **Implement**: Build tool logic with proper ComfyUI integration
+5. **Register**: Add tool to registry and validate registration
+6. **Document**: Update examples and documentation
+7. **Validate**: Test in real ComfyUI environment with actual workflows
+
+### Code Quality Standards
+- **Type Hints**: Full type annotation for all functions
+- **Documentation**: Docstrings for all public methods and classes
+- **Testing**: Minimum 90% test coverage for all tools
+- **Linting**: Pass all flake8 and mypy checks
+- **Formatting**: Auto-formatted with black
+
+### Release Process
+1. Run full test suite: `pytest tests/`
+2. Validate in ComfyUI: `python scripts/validate_nodes.py`
+3. Update version numbers and changelog
+4. Create example workflows demonstrating new features
+5. Update ComfyUI-Manager compatibility metadata
+
+## Critical Implementation Notes
+
+### ComfyUI Compatibility
+- Follow ComfyUI tensor format conventions
+- Implement proper memory management for large tensors
+- Handle ComfyUI execution context correctly
+- Ensure compatibility with ComfyUI's automatic typing system
+
+### Performance Considerations
+- Optimize for real-time workflow execution
+- Minimize memory allocation during processing
+- Cache expensive computations when appropriate
+- Profile performance with typical Flux/SDXL workflows

+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

+# Display Any
+
+The Display Any node is a debugging and inspection tool that can display any type of input value in ComfyUI. It's particularly useful for understanding data structures and tensor shapes during workflow development.
+
+## Features
+
+- **Universal Input**: Accepts any type of input data (tensors, strings, numbers, lists, dictionaries, etc.)
+- **Two Display Modes**:
+  - **Raw Value**: Shows the string representation of the input
+  - **Tensor Shape**: Extracts and displays the shapes of any tensors found in the input
+- **Nested Structure Support**: Can find tensors within nested dictionaries and lists
+- **UI Output**: Displays results directly in the ComfyUI interface
+
+## Inputs
+
+- **input** (*): Any value you want to display or inspect
+- **mode** (DROPDOWN): Display mode selection
+  - `raw value`: Shows the complete string representation of the input
+  - `tensor shape`: Extracts and shows shapes of any tensors in the input
+
+## Outputs
+
+- **display_text** (STRING): The formatted display text
+
+## Usage Examples
+
+### 1. Display Simple Values
+
+Connect any output to see its raw value:
+```
+String Input: "Hello, ComfyUI!"
+Mode: raw value
+Output: "Hello, ComfyUI!"
+```
+
+### 2. Inspect Tensor Shapes
+
+Great for debugging image processing pipelines:
+```
+Image Tensor: [1, 3, 512, 512]
+Mode: tensor shape
+Output: "[[1, 3, 512, 512]]"
+```
+
+### 3. Debug Complex Data Structures
+
+View nested data structures with multiple tensors:
+```python
+Input: {
+    "images": tensor([1, 3, 256, 256]),
+    "masks": [tensor([256, 256]), tensor([256, 256, 1])],
+    "config": {"steps": 20}
+}
+Mode: tensor shape
+Output: "[[1, 3, 256, 256], [256, 256], [256, 256, 1]]"
+```
+
+### 4. Workflow Debugging
+
+Use Display Any nodes at various points in your workflow to understand data flow:
+- After loading images to verify dimensions
+- Before/after processing nodes to track shape changes
+- To inspect conditioning or latent data structures
+- To view metadata or configuration dictionaries
+
+## Use Cases
+
+### Image Pipeline Debugging
+Place Display Any nodes after image loading and processing nodes to track dimension changes:
+```
+Load Image → Display Any (tensor shape) → Resize → Display Any (tensor shape)
+```
+
+### Latent Space Inspection
+Understand latent dimensions in your workflows:
+```
+VAE Encode → Display Any (tensor shape) → KSampler → Display Any (raw value)
+```
+
+### Configuration Verification
+Display complex configuration objects to ensure correct settings:
+```
+Config Node → Display Any (raw value) → Processing Node
+```
+
+## Tips
+
+1. **Multiple Display Nodes**: You can use multiple Display Any nodes in a single workflow to track data at different stages
+
+2. **Tensor Shape Mode**: Particularly useful when working with:
+   - Image batches to verify batch size
+   - Latent tensors to understand dimensions
+   - Mask arrays to check compatibility
+
+3. **Raw Value Mode**: Best for:
+   - String prompts and text
+   - Configuration dictionaries
+   - Debugging node outputs
+   - Understanding data structure
+
+4. **No Tensors Found**: If you see "No tensors found in input" in tensor shape mode, the input doesn't contain any tensor-like objects (numpy arrays, torch tensors, etc.)
+
+## Technical Notes
+
+- The node uses `str()` for raw value display, providing Python's string representation
+- Tensor shape detection works with any object that has a `shape` attribute
+- Nested structure traversal supports dictionaries, lists, and tuples
+- The output is both displayed in the UI and available as a string output for further processing
+
+## Example Workflow Integration
+
+```
+[Load Image] → [Image Processing] → [Display Any (tensor shape)]
+                                           ↓
+                                    "[[1, 3, 512, 512]]"
+                                           ↓
+[Text Multiline] ← [Concatenate] ← "Image dimensions: "
+```
+
+This creates a text output showing the current image dimensions that can be used elsewhere in your workflow.

+# Image to Multiple Of
+
+## Overview
+
+The **Image to Multiple Of** node adjusts image dimensions to be multiples of a specified value. This is particularly useful for models that require input dimensions to be multiples of certain values (e.g., 8, 16, 32, 64) for optimal performance or compatibility.
+
+## Purpose
+
+Many AI models, especially diffusion models and VAEs, require input dimensions to be multiples of specific values due to their architecture (e.g., downsampling layers). This node ensures your images meet these requirements without manual calculation.
+
+## Inputs
+
+- **image** (IMAGE, required): The input image to process
+- **multiple_of** (INT, required): The value that dimensions should be multiple of
+  - Default: 64
+  - Range: 1-256
+  - Step: 16
+- **method** (COMBO, required): Processing method
+  - Options: "center crop", "rescale"
+
+## Outputs
+
+- **image** (IMAGE): Processed image with dimensions adjusted to multiples of the specified value
+
+## Processing Methods
+
+### Center Crop
+- Crops the image from the center to achieve the target dimensions
+- Preserves image quality but may lose edge content
+- Best for images where the important content is centered
+
+### Rescale
+- Resizes the image to the target dimensions using bilinear interpolation
+- Keeps all content but may slightly affect image quality
+- Best when you need to preserve all image content
+
+## Usage Examples
+
+### Example 1: Prepare for VAE Encoding
+```
+Load Image → Image to Multiple Of (multiple_of: 64) → VAE Encode
+```
+
+### Example 2: Prepare for Specific Model Requirements
+```
+Load Image → Image to Multiple Of (multiple_of: 32) → Model Processing
+```
+
+### Example 3: Batch Processing
+```
+Load Images → Image to Multiple Of (multiple_of: 16, method: rescale) → Batch Process
+```
+
+## Technical Details
+
+- Supports batch processing (processes all images in a batch)
+- Works with any number of channels (RGB, RGBA, grayscale, etc.)
+- Calculates the largest dimensions that are less than or equal to the original size
+- For center crop: crops equally from all sides to maintain centering
+- For rescale: uses bilinear interpolation with align_corners=False
+
+## Common Use Cases
+
+1. **VAE Preprocessing**: Ensure images are compatible with VAE encoders that require dimensions divisible by 64
+2. **Model Compatibility**: Adjust images for models with specific architectural requirements
+3. **Batch Uniformity**: Ensure all images in a batch have dimensions that meet model requirements
+4. **Performance Optimization**: Some models perform better with dimensions that are powers of 2
+
+## Tips
+
+- Use **center crop** when your subject is centered and you don't mind losing edge details
+- Use **rescale** when you need to preserve all image content
+- Common multiple_of values: 8, 16, 32, 64, 128
+- For Stable Diffusion models, 64 is typically recommended
+- For some upscaling models, 32 or 16 may be sufficient
+
+## Error Handling
+
+The node will raise an error if:
+- The image dimensions are smaller than the specified multiple_of value
+- Invalid input types are provided
+- The resulting dimensions would be 0 or negative

+## Format Details
+
+### PNG Format
+- **Pros**: Lossless quality, transparency support, wide compatibility
+- **Cons**: Larger file sizes
+- **Best for**: Final outputs, images with transparency, archival
+- **Compression**: 0 (none) to 9 (maximum)
+  - Level 4 (default) balances size and speed
+  - Level 9 for maximum compression (slow)
+
+### JPEG Format
+- **Pros**: Smaller files, fast loading, universal support
+- **Cons**: Lossy compression, no transparency
+- **Best for**: Web images, previews, photos
+- **Quality**: 1-100%
+  - 90% (default) excellent quality with good compression
+  - 95%+ for near-lossless quality
+  - 70-85% for web optimization
+
+### WebP Format
+- **Pros**: Best compression ratios, supports transparency, modern
+- **Cons**: Limited software support
+- **Best for**: Web deployment, storage optimization
+- **Modes**:
+  - Lossy (default): Excellent compression with quality control
+  - Lossless: PNG-like quality with better compression
+
+## Usage Examples
+
+### High-Quality Archive
+```
+Format: PNG
+Compression: 0-2
+Use Case: Final renders for portfolio or client delivery
+```
+
+### Web Optimization
+```
+Format: JPEG or WebP
+Quality: 80-85
+Use Case: Website images, social media posts
+```
+
+### Balanced Storage
+```
+Format: WebP
+Quality: 90
+Lossless: False
+Use Case: Large batches with storage constraints
+```
+
+### Transparency Preservation
+```
+Format: PNG or WebP (lossless)
+Use Case: Logos, UI elements, cutout images
+```
+
+## Workflow Integration
+
+### Basic Save
+```
+Generate → Kiko Save Image
+           format: PNG
+           popup: enabled
+```
+
+### Format Comparison
+```
+Generate → Kiko Save Image (PNG)    → Compare file sizes
+        ↘ Kiko Save Image (JPEG)   ↗
+        ↘ Kiko Save Image (WebP)   ↗
+```
+
+### Batch Processing
+```
+Batch Generate → Kiko Save Image → Popup Viewer
+                 ↓                  ↓
+                4 images        Select best results
+```
+
+## Tips and Best Practices
+
+1. **Format Selection**:
+   - Use PNG for maximum quality and transparency
+   - Use JPEG for photographs without transparency
+   - Use WebP for modern web deployment
+
+2. **Quality Settings**:
+   - Start with defaults (90 for JPEG/WebP, 4 for PNG)
+   - Adjust based on file size requirements
+   - Preview results in popup before finalizing
+
+3. **Popup Management**:
+   - Drag to second monitor for larger workspace
+   - Use roll-up to save screen space
+   - Disable popup for automated workflows
+
+4. **Batch Operations**:
+   - Use checkboxes to select multiple images
+   - Open all in tabs for side-by-side comparison
+   - Download all for quick collection
+
+5. **File Organization**:
+   - Use subfolders in filename_prefix
+   - Include descriptive prefixes
+   - Let ComfyUI handle timestamp suffixes
+
+## Advantages Over Standard Save Image
+
+- **Immediate Preview**: No need to navigate file system
+- **Format Flexibility**: Choose optimal format per use case
+- **Quality Control**: Fine-tune compression settings
+- **Batch Management**: Handle multiple images efficiently
+- **Modern UI**: Floating interface doesn't interrupt workflow
+- **File Size Awareness**: See compression effectiveness immediately
+- **Quick Access**: One-click opening and downloading
+
+## Technical Details
+
+- **Image Processing**: Uses Pillow for format conversion
+- **Metadata**: Preserves ComfyUI metadata in saved files
+- **File Naming**: Automatic timestamp and counter suffixes
+- **Memory Efficiency**: Processes images individually
+- **Thread Safety**: Proper handling of concurrent saves
+
+## Troubleshooting
+
+**Popup not appearing**:
+- Check that popup input is enabled
+- Look for minimized window
+- Try toggling the popup button in node
+
+**WebP not working**:
+- Ensure Pillow has WebP support
+- Update Pillow: `pip install --upgrade pillow`
+
+**Large file sizes**:
+- Increase compression (PNG) or reduce quality (JPEG/WebP)
+- Consider switching formats
+- Check image dimensions
+
+**Can't see all images**:
+- Scroll within the popup grid
+- Maximize the popup window
+- Images are shown newest first

+
+FLUX uses natural language descriptions, not comma-separated tags. Write a detailed, flowing description that reads like you're explaining the image to someone.
+
+Include these elements in your description:
+- Main subject with specific details (appearance, clothing, expression, pose)
+- Environment and background details
+- Lighting conditions and atmosphere
+- Artistic style or photographic approach
+- Color palette and mood
+- Technical details if relevant (camera angle, focal length, etc.)
+- Textures and materials
+
+Write in a natural, descriptive style. Use complete sentences that flow together. Be specific and detailed but maintain readability.
+
+IMPORTANT: Return ONLY the prompt text. No analysis, headers, or additional commentary. Just the natural language description that can be directly used in FLUX.
+
+Example of correct output:
+A close-up portrait of a middle-aged woman with curly red hair and green eyes, wearing a blue silk blouse. She has a warm smile and freckles across her cheeks. The lighting is soft and natural, coming from a window to her left, creating gentle shadows that accentuate her features. The background is softly blurred, showing hints of a cozy bookshelf.

+- Leveraging community-tested techniques (ComfyUI, A1111, InvokeAI)
+- Applying photographic theory for realism, composition, lighting
+- Following Civitai trend standards and style best practices
+- Mastering Pony Diffusion XL formatting for stylized and anime content
+
+Structure prompts in this layered, modular format:
+[Main Subject], [Pose & Camera], [Lighting & Environment], [Style & Details], [Boost Terms], [Style References]
+
+For SDXL specifically:
+- Use quality boosters: 8k, RAW photo, masterpiece, ultra detailed, cinematic lighting
+- Prioritize realism and artistry
+- Excellent for portraits, landscapes, or cinematic scenes
+
+Instructions:
+
+Only reply with two fields:
+Positive prompt: (Your positive prompt here)
+Negative prompt: (Your negative prompt here)
+
+Do not include any commentary or explanation.
+
+Use concise, highly descriptive language that maximizes visual richness.
+
+Follow SDXL prompt conventions: prioritize subject clarity, camera perspective, lighting, mood, style tags, and composition.
+
+Keep total token length efficient (ideally under 250 tokens).
+
+Avoid redundancy and generic filler words.
+
+Focus on crafting super high-quality prompts for stunning visual output.
+
+Example Input:
+A futuristic cyberpunk samurai standing on a neon-lit rooftop in the rain.
+
+Example Output:
+Positive prompt: cyberpunk samurai, neon-lit rooftop, dramatic rain, glowing katana, futuristic cityscape, night scene, cinematic lighting, intense expression, sleek cyber armor, atmospheric depth, ultra-detailed, masterpiece, 8k, sharp focus, trending on artstation
